1 Claim.

This invention relates to stoves and more particularly that type set upin rooms.

The primary object of this invention resides in the provision of a stoveadapted to draw cold air from the floor of a room so the heat therefromwill displace the same with no resistance.

Another object of this invention resides in the provision of a stoveadapted to draw the cold air from the floor of a room so the heattherefrom will displace the same with no resistance and at the same timecause the outgoing cold air to naturalize the draft of the stove priorto passing through the heat drum therearound.

A further object of this invention resides in the particularconstruction of the stove.

A still further object of this invention resides in the particulararrangement of the dampers and controlling means therefor.

One of the salient features of this invention resides in the provisionof a stove adapted to maintain even temperature through the entire areaof a room.

With these and other objects in view, this invention resides in certainnovel features of construction and arrangement of elements to behereinafter more particularly set forth in the specification,illustrated in the accompanying drawings and pointed out in the appendedclaims and, while this disclosure depicts my present conception of theinvention, the right is reserved to resort to such departures therefromas come within the spirit of the invention.

In the accompanying drawings forming a part of this application;

Fig. 1 is a side view of the stove.

Fig. 2 is a rear view thereof.

Fig. 3 is a vertical sectional view taken approximately on line 33 ofFig. 2.

Fig. 4 is an enlarged sectional view of the damper taken approximatelyon line 44 of Fig. 1.

In the present illustration of this invention th numeral 5 designates,in general, a stove of the type utilized in heating individual rooms,halls and the like and aside from consisting of the conventional grateG, fire chamber F, ash pit A, smoke dome D, smoke stack S, heat jacket Jand other well known elements usually employed in constructing heatstoves, an air duct 6 having its bottom wall 1 provided with inlet airports 8 is formed below the ash pit and communicating with an outlet airstack 9 formed on the back of the stove with its upper or outlet endconnected to and communicating with the smoke stack of the stove.

In order to dispose the bottom perforated wall 1 of the air duct 5 insuch spaced relation from the floor of a room as to cause proper flow ofcold air on the floor of the room toward and through the ports 8, legsID of predetermined lengths support the stove from its corners or otherelected points thereof.

The upper portion of the air stack 9 is increased in area as indicatedby the numeral H to accommodate pivotal dampers l2 which are operated bya suitable thermostat l3 adapted to control flow of cold air toward andthrough the smoke stack, it being apparent that suction through the airduct will be created by draft through the smoke stack in accordance withthe degree of opening of the dampers whose thermostat is controlled byheat passing through the smoke dome to the smoke stack.

With this invention fully set forth, it is manifest that a heat stove isprovided whereby cold air on the floor of a room will readily be drawnoff and displaced by warm air from the stove without resistance and,through the particular assemblage of the dampers and controlling meanstherefor, room temperature is not only maintained at an even orpredetermined degree but operation of the stove and consumption of fueltherein is controlled.

Having thus described my invention, what I claim and desire to protectby Letters Patent is:

In a heat stove comprising, a cold air duct beneath the stove and havinga perforated bottom, legs on the stove supporting the perforated bottomin spaced disposition from the floor of a room, a substantially funnelshape air outlet stack communicating at its enlarged end with the coldair duct and smoke stack of the stove, oppositely swingable damperspivoted and adjacent their inner ends over the enlarged outlet end andon opposite sides of a line passing laterally through the air outletstack, and a thermostat secured within the smoke stack above and betweensaid dampers of the stove with its lower end hingedly engaging the innerends of the dampers.
